SPECIFICATION forming part O Letter Patent NO. 645,451, dated. March 13,1900. Application filed October 18, 1899. Serial No. 734,024. (Nomodel.)

To @ZZ whom t may concern:

,PAscHAL E. WILHrrE, citizens of the United States, residing at MountHope, in the county of Sedgwickand State of Kansas, have inventedcertain new and useful Improvements in Tanks; and we do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the saine.

This invention relates to a new and useful improvement in watering-tanksfor use Aby live stock; and its object, among other things, is toprovide a tank of simple and durable construction with means to preventfreezing of the contents of the tank during cold weather. v 1

To these ends the invention consists in con-- structing the tank with,preferably, a coneshaped bottom and a due extending upward therefromthrough the center of the tank to a point above the upper edge thereof 5also, in providing means whereby the side of the tank may bestrengthened to resist any pressure which might be brought to bearthereagainst by the stock while drinking, 85e.

The invention also consists in the further novel constructions andcombinations of parts hereinafter more fully described and claimed, andillustrated in the accompanying drawings, showing the preferred form ofour invention, and in which- Figure l is a perspective view of our im-yproved tank with cover removed. Fig. 2 is a central vertical sectionthrough the tank and its cover.

' Referring to said figures by letters of reference, A is the side ofthe tank, which is formed of any suitable material, as galvanized iron,steel, duc., and B is the bottom thereof, preferably cone-shaped,asshown, and secured to the side by means of rivets or in any otherdesired manner. A liuc O extends upward from the center of the bottom,with which it communicates, to a point above the upper edge of the sideA and is provided with a suitable damper, as D, whereby the drafttherethrough may be regulated as desired.

Within the chamber E, formed by the coneshaped bottom B, is located asuitable device, as F, whereby the tank may be conveniently andexpeditiously heated. This heating dep vice may consist of a smallfurnace constructed of boiler-iron or masonry, or, if desired, a lamp ofsuitable size may be placed within the chamber.

By means of the damper D the heat Within the chamber E can be regulated,and by providing a cone-shaped bottom B the maximum amount of surface isexposed to the heat, which is also capable of reaching all points uponthe bottom of the tank.

To the upper edge of the side A of the tank is riveted an angle-iron, asG, which serves to brace the side against any pressure which might beexerted thereagainst by the stock.

If desired, a cover, as H, may be provided for the tank. This can beutilized for retaining the heat within the water when the tank is not inuse.

While we have described our tank as adapted for watering stock, it is tobe understood that the same may also be utilized for soaking corn or forcooking feed, if so desired.

The furnace F, which We have illustrated in the drawings, is preferablysemicircular in cross-section, as shown, and is provided with achimneyF', which extends into the ue C, as shown.

In the foregoing description We have shown the preferred form of ourinvention; but we do not limit ourselves thereto, as we are aware thatmodifications may be made therein Without departing from the spirit orsacrificing the advantages thereof, and we therefore reserve the rightto make such changes as fairly fall within the scope of our invention.

Having thus fully described our invention, what we claim, and desire tosecure by Letters Patent, is-

In a watering-tank, the combination, with the side, having strengtheningmeans at its upper edge, of a conical bottom forming a chamberthereunder, a furnace within said chamber, a flue extending from thebottom to a point above the upper edge of the side, a chimney to thefurnace projecting into the flue, a damper in said flue, and a cover,substantially as described.

In testimony whereof we ax our signatures in presence of two witnesses.
